# /develop - Multi-Phase Feature Development

Build features through structured phases with validation gates.

## Feature: $ARGUMENTS

### Phase 1: Research

Explore the codebase to understand the scope:

1. Find all relevant files and existing patterns
2. Check dependencies and constraints
3. Score confidence across 5 dimensions (0-100)

**Scoring:**
- Scope clarity (0-20): Know exactly what files change?
- Pattern familiarity (0-20): Similar patterns exist?
- Dependency awareness (0-20): Know what depends on changed code?
- Edge cases (0-20): Can identify the edge cases?
- Test strategy (0-20): Know how to verify?

**Decision:**
- Score >= 70 → Present research findings and move to Phase 2
- Score < 70 → Identify gaps, gather more context, re-score

### Phase 2: Plan

Present a plan for approval:
